Is it possible to create approval form with signature field?

Is there a way to set up the form so that upon submittal by client, it gets sent to me to approve what they inputted and then give my final signature.  And then I can send that back to them with my signature?

Yes, that is possible. What you need to do is to create an approval form, so please refer to this guide: https://www.jotform.com/help/432-A-General-Approach-on-Building-an-Approval-Process-Workflow

It has a signature field included as well.
